FASTENING FOR RAIL BONDS.

Application filed November 13, 1924. Serial No. 749,641.

My invention relates to fastenings particularly suitable for securing railway rail bonds in position upon the rails, although it may be used in other relations.

One object of my invention is to provide an improved form of clip and terminal construction whereby bonds may be more effectively and conveniently secured than in the case of various devices heretofore employed.

Another object of my invention is to provide an improved form of clip for securing the terminals of rail bonds to the rails.

Some of the forms which my invention may take are shown in the accompanying drawings wherein Fig. 1 is a perspective view showing a rail bond secured in position upon a rail, through employment of my invention; Fig. 2 is an enlarged view of a port-ion of the bond proper of Fig. 1; Fig. 3 is a view, partially in section, of one of the terminals of Fig. 1; Fig. 4 is an end elevational view of a portion of the apparatus of Fig. 1; Fig. 5 1s a cross sectional view, on an enlarged scale, of the terminal member welded in position upon the rail flange; Fig. 6 is a view showing the form of clip preferably employed in connection with the terminals of Figs. 1 to 5; Flg. 7 is a View similar to that of Fig. 1 but showing a modified form of clip and terminal structure; Fig. 8 is a plan View, on an enlarged scale, of a portion of the apparatus of Fig.

7; Fig. 9 is an end elevational view of the apparatus of Fig. 7 and Fig. 10 is a view showing the form of clip employed in Figs. 7 to 9.

My invention is shown as applied to railway rails 11 connected by splice bars 12 and comprises a flexible conductor 13, of copper or the like, provided with terminals 14 which may be of mild steel. The form and manner of making the terminals 14 form the basis of an application filed by me on November 13, 1924, Serial No. 749,640, now Patent No. 1,634,689. Clips 15, preferably stamped from sheet metal are. employed for holding the terminals 14 in position uponrails. The conductors 13 are fused or otherwise tightly secured in the sleeve-like members 14.

The clips 15 are provided with a tongue 16 adapted to engage the underside of the rail and with an overhanging or hook portion 17 that fits over the upper rounded surface of the terminals 14. The conductor 13 is placed A CORPORATION or in position upon the splice bar 12 as shown on top of the base spliced bar 12 without undue distortion or bending. With the termlnals 14 in position upon the rail flange, adacent to the outer edge thereof, the clips 15 are placed in position and hit a sharp blow with a hammer to move them toward the webs of the rails 11, carrying with them the terminals 14. The wedge-shape form of the flanges cause a wedging action, thus insuring a tight engagement between the parts. Furthermore, the inclined position of the upper surfaces of the terminals 14 skews the clips somewhat so that a further binding or biting action between the edges of the tongues 15 and the rail flanges is secured. Also the stamping out of the clips leaves roughened corners on the inner edges of the tongue portions and these edges or corners exercise a still further biting action. If desired, the terminals 14 may first be placed at nearly the desired distance from the edge of the rail flange and the clips 15 first moved longitudinally thereof, along the upper inclined surfaces of the terminals and then driven inwardly.

The fastening thus effected may be a temporary one or may be made more permanent by welding eitherthe clip to the rail, or by welding the terminals 14 thereto by depositing welding metal at the points 18 as indicated in Figs. 4 and 5.

Referring now to Figs. 7 to 10, the rail sections 11' and the splice bars 12 are as shown in Fig. 1, but I provide terminals 14 of a different form than the terminals 14. These terminals have the conductor 13 secured thereto in any desired manner and are provided with cut-out or tongue portions around the edges of which welding metal may be deposited for securing them to the rail flanges. This latter feature is made the subject of a separate application for patent filed by me November 13, 1924, Serial No. 749,689.

The terminals 14 are placed in position upon the rail flanges as shown in Fig. 1 and terminal clips 15 driven into position to hold the terminals in place. The clips 15 are provided with tongue portions 16 and 17 a that engage the underside of the rail and tops of the terminals 143. As shown more clearly in Fig. 8, that portion of the terminal 14 that rests upon the rail flange is angularly disposed so that the clips l5 may be more readily applied. The clips may be permitted to remain in position, or the terminals 14 may be welded to the rail flanges and the clips removed. 'The outer sides of the terminals 14 may be bent downwardly to a position under the rail, in a manner described in my co-pending application last above referred to. .7 v

It will be understood that the fastening means may be employed with other devices than rail bonds, and that various changes in detail and general arrangement may be made without departing from the spirit and scope as defined in the accompanying claim.

I claim as my invention:

A rail bond structure comprising in combination a rail having a fiangetapered on the upper side thereof and having its, underside at right angles to the vertical center line running through the web of the rail, a bond provided with tapered terminals having a plain face for engaging the upper side of the rail flange and a flat metal clamp having a cut-out portion complementary in shape to the portion of the terminal and rail which it is adapted to engage, said clamp being adapted to securely grip the bond terminal and rail flange in clamping engagement when driven on said flange.

In'testimony whereof I, the said EDUARD SCHENK, have hereunto set my hand.
